That seems very unsatisfying to me, especially because I can easily
reproduce the problem with 'make -j2 all'.

I think unpredictable hangs are much worse than manually maintaining
dependencies.  We can always try again in a couple years, after a new
make is released.

I'm bootstrapping the reversion on a couple machines now.  I will send
it before the end of the day.
